1 Claim.

The principal object of the present invention is to provide a method and means for producing chenille thread and more particularly directly upon the loom in which the fabric from which the threads are formed is woven.

An important object of the present invention is to provide a simple method whereby chenille threads can be produced inexpensively. During the course of the following specification and claim other important objects and advantages of the invention will become apparent to the reader.

In the drawings:

Figure 1 represents a fragmentary top plan view of the means mounted on a loom whereby the fabric produced by the loom is cut.

Figure 2 represents a side elevational View fragmentarily showing the structure represented in Figure 1.

Figure 3 represents a vertical sectional view of the structure shown in Figure 1.

Figure 4 represents a fragmentary detailed sectional view taken substantially on the line 4-4 of Figure 3.

Figure 5 represents a fragmentary plan view of the woven fabric from which the chenille thread is produced.

Figure 6 represents a fragmentary side elevational view of a thread produced by cutting the fabric shown in Figure 5 in accordance with the present invention.

Referring to the drawings wherein like numerals designate like parts, it can be seen that V the numeral 5 represents the lay of the loom while ing and tightening the screw 19 proper adjust' numeral 6 represents the usual reed, neither of which forms any part of the present invention. Figure 3 discloses the woven fabric 8 passing from the reed and over the guide bar 9 from where it extends downwardly to pass under the roller 10, around the sand roller 11 and against the roller 12 from where it travels to a winding device.

The loom involves the breast plate 13 grooved to receive the base plate 14.

Upon this base plate 14 are mounted the different cutting units generally referred to by numeral 15.

Each cutting unit includes an angle 16 secured to the base plate 14 by a screw 17 passing through a slot therein to thread into the base plate 14.

Each of these cutting units is on the supporting arm 18 which is slotted at one end to receive the screw 19 which threads into the upstanding part of the angle 16 and in this manner by loosenment of the arm 18 can be secured.

Each arm 18 at its outer end is provided with a bearing 20 having a bushing 21 therein through which extends the shaft 22, the same being equipped at one end with a pulley 23. A pressed collar or circumferential rib 24 on the intermediate portion of the shaft limits thrust of the shaft while between this point and the opposite end of the shaft are located the disk cutter blades 25, each of which is provided with a double beveled edge 26.

Between the blades of each unit are located the spacing collars 27 while at the last mentioned end of the shaft a further extension 28 is provided for accommodating the nut 29 which clamps the ring 30 against the blades so that the blades are firmly held between the thrust collar 24 and the ring 30.

As is clearly shown in Figure 1, numeral 31 represents the drive shaft which at intervals corresponding to the places where the units 15 are located, is provided with pulleys 32. Trained over these pulleys 32 on the corresponding pulleys 23 are the crossed belts 33. The shaft 31 thus serves to drive all of the units 15, and is supported by end bearings 34.

One end of this shaft 31 is equipped with a pulley wheel 35 and a crossed belt 36 laid over this pulley 35 and the pulley 3'7 on the armature shaft of the motor 38 affords a driving connection between the motor 34, located on the support 39, and the aforementioned shaft 31.

The loom is intended to produce a fabric such as is generally referred to by numeral 40 in Figure 5. The fabric evolves multiple strand warps and single strands when the warps are spaced apart to the extent substantially shown in Figure 5 and as is apparent in Figure 4, there is just one more warp than there are blades 25 and corresponding cutting unit 15.

As is further apparent in Figure 4, it can be seen that the blades at their cutting edges will intersect the plane on which the fabric travels (see Figure 3) and as the weft strands pass under the knives they are severed at a number of points equal to one less than the number of warps. As is apparent in Figure 4, the fabric will be guided and there will be slight likelihood of the warp threads being cut because the warp strands will find their way between the cutter blades and pressure will be exerted mainly against the weft strands to the end, that the weft strands will be cut on lines running substantially parallel to the warp and in equal spaced relation with respect thereto, so that the resulting thread is Having thus described our invention, what we claim as new is:

In combination, a loom, a cutter on the loom for cutting fabric on parallel lines between the warp strands of the fabric produced by the loom, said cutter including a disk blade, means for driving the blade, and an adjustable mount for the said blade for adjusting the blade with respect to the fabric to obtain the proper tension of the fabric against the blade, said mount consisting of an angle member having an upstandstanding portion, an arm adjustably connected to said upright portion and provided with a hearing at its outer end, a shaft disposed through said bearing and provided at one end with a drive pulley, said cutter being mounted on the opposite end of the said shaft.
